Description

Technical Field

[0001] The present invention relates to the technical field of fire detection equipment, and particularly to a device for detecting the sealing effect of a fire hose for fire detection. Background Art

[0002] A fire hose is a flexible hose used to transport high-pressure water or flame-retardant liquids such as foam. As a crucial part of fire-fighting equipment, a fire hose is an important tool for firefighters to connect water and extinguish fires in case of a fire. If the fire hose is not detected for a long time, it is prone to breakage problems, resulting in serious water leakage when using the fire hose and affecting normal fire-fighting operations.

[0003] When the applicant applied for the present invention, after retrieval, it was found that a Chinese patent disclosed an "airtightness detection device for a fire hose" with an application number of "202023196680.9". This patent mainly realizes the automatic winding of the fire hose through the setting of the structure, enabling the user to better observe the process of fire hose detection and thus improving the overall detection accuracy of the structure. However, when detecting the airtightness of the fire hose, there is a lack of treatment for the soil or debris on the surface of the fire hose. The debris adheres to the outside of the fire hose, which is likely to affect the detection effect. If the debris just adheres to the through hole, it cannot be detected. Summary of the Invention

[0017] (III) Advantageous effects

[0018] The present invention provides a device for detecting the sealing effect of a fire hose for fire detection. It has the following advantageous effects:

[0019] 1. By arranging the friction plate and the lower friction plate in cooperation, the fire hose passes through between the friction rod and the lower friction plate. During the passing process, the debris or dirt on the surface of the fire hose is cleaned by the friction plate and the lower friction plate, keeping the exterior of the fire hose clean and facilitating the detection of the air tightness of the fire hose.

[0020] 2. By arranging the collecting roller, the pressing block, the scraping plate and the groove in cooperation, a part of gas is filled into the fire hose, and the fire hose is pressed tightly by using the cooperation of the pressing block and the groove to avoid gas leakage. Then, it is wound and collected by the collecting roller. During the collecting process, the fire hose moves between the pressing block and the groove, and the gas moves along with the collection of the fire hose, thereby detecting the air tightness of the fire hose. Moreover, the scraping plate and the groove can handle the excess dirt, ensuring the accuracy of the detection effect.

[0021] 3. By arranging the limit clamp, using the cooperation of the limit clamp and the telescopic rod, and with the cooperation of the second threaded rod and the second threaded block, the limit clamp can be driven to move. The limit clamp can be used to limit the fire hose, keeping the fire hose stable during the movement and facilitating the observation of the air tightness of the fire hose.

The first bevel gear 50 and the second bevel gear 51 are meshed with each other.

[0042] Working principle: When in use, place the fire hose outside the feeding roller 36, pass the fire hose through the middle of the water tank 2, and successively pass through the outside of the two limiting rollers 42, between the friction plate 43 and the lower friction plate 40, between the scraping plate 37 and the groove 41, between the pressing block 38 and the groove 41, and finally pass through the middle of the collecting roller 5.

[0043] Drive the first bevel gear 50 and the second bevel gear 51 to rotate by using the third motor 25, so that the second threaded rod 48 rotates, and the second threaded block 49 drives the telescopic rod 34 to move, thereby driving the limiting fixture 31 to move, and use the limiting fixture 31 to limit the fire hose, so that the fire hose remains stable during the movement;

[0044] And use the second electric rod 15 to push the second movable plate 26 to move, so that the scraping plate 37 cooperates with the surface of the fire hose, and the sundries remaining on the surface of the fire hose can be processed;

[0045] Moreover, before the air tightness test of the fire hose, use the third electric rod 16 to push the third movable plate 46 to move, so that the friction plate 43 cooperates with the lower friction plate 40, and the sundries on the surface of the fire hose can be cleaned during the friction process, which is convenient for the air tightness test of the fire hose;

[0046] Use the first electric rod 11 to push the first movable plate 7 to move, so that the pressing block 38 cooperates with the groove 41. Drive the collecting roller 5 to rotate by using the first motor 22, and collect the fire hose during the rotation. And the gas inside the fire hose moves under the action of the pressing block 38 and continuously moves inside the fire hose. Since the inside of the water tank 2 is filled with water, if the fire hose has holes, bubbles will occur, which is convenient for the air tightness test of the fire hose.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
